Built for Constellation Software
Everything payments.
One Platform
CSIPay Gateway is Constellation Payments’ embedded payments platform, built exclusively for Constellation Software and Jonas Group operating companies. Integrate payments directly into your product, without building or managing the infrastructure yourself.
Why CSIPay?
The shared payments platform that eliminates duplication and accelerates go-to-market
Handing payments away
Most software companies hand payments to a third party, and hand over the upside too. Operating companies that rely on outside processors do not control the merchant relationship, which limits visibility, flexibility, and pricing transparency. When processors change fees or terms, partners have little ability to protect their customers or manage the experience. Fragmented integrations make it hard to standardize workflows, reporting, and support across the portfolio.
One shared platform
CSIPay centralizes payments as a shared platform across the Constellation ecosystem. Partners integrate once and gain the full payment lifecycle while keeping control of the customer facing experience. Processing, compliance, risk controls, and settlements are handled behind the scenes, so each company stays focused on its product.
No duplicated effort
Without a shared platform, every operating company rebuilds the same effort, cost, and risk. CSIPay removes that duplication, so partners launch faster, hold consistent security and compliance standards, and scale across the ecosystem without each company building its own financial infrastructure.

Automated risk and compliance checks are applied before routing to card networks or ACH.
Capture and settlement
Approved transactions are batched and settled through card or ACH rails, typically within one to three business days.
Funding and payouts
Net funds move to merchant bank accounts on the configured payout schedule.

Track transactions, settlements, payouts, refunds, and chargebacks in a unified card and ACH view.
